Answer 1

Answer:

The answer is -

Step-by-step explanation:

To find the value of B

49$a^{2}$ - b = (7a + 1/3)(7a - 1/3)

Follow the identity $a^{2}$ - $b^{2}$ = (a + b)(a - b)

$(7a)^{2}$ - $(?)^{2}$ = (7a + 1/3)(7a - 1/3)

? = 1/3

We have to find the value of B

b = $(1/3)^{2}$

  = 1/9[Value of b]
